Open data standards in risk modelling are believed to be the most effective and transparent

Aon has announced the implementation of the Open Exposure Data (OED) Standard curated by Oasis for the risk modelling of property reinsurance placements.

Led by Aon, RenaissanceRe, SCOR, Hannover Re and Swiss Re, the OED Standard is a non-commercial venture designed to test and support the hypothesis that open data standards in risk modelling are more effective than proprietary and commercial standards in terms of improving operational efficiency, reducing costs and increasing transparency and consumer choice.

Collaboration milestone

Dan Dick, executive managing director and global head of property analytics for Aon’s Reinsurance Solutions, said: ”This announcement exemplifies the ways in which our industry is making a positive impact in our communities and for our fellow citizens, by collaborating and focusing on critical issues where we can apply our energy and expertise to make a meaningful difference by informing better decisions.”

The OED Standard will also lower barriers of entry for model developers – including commercial vendors, third-party data providers and academia and other research institutions.

Initial testing on reinsurance placement data for Japan, Australia and China has proved successful as the initiative broadens its area of focus. 

The re/insurance industry collaboration is designed to promote equality and inclusion when accessing critical risk information, allowing communities globally to become more risk-aware and risk-informed, while improving their resiliency and ability to save lives.

Ian Branagan, EVP and group chief risk officer at RenaissanceRe and co-chair of the Insurance Development Forum Risk Modelling Steering Group, added: “This is an outstanding example of continuing industry collaboration to drive the democratisation of risk insight around the world.”

A win for societal resilience

Paul Nunn, head of Sustainable Insurance, SCOR, said he hoped the data standards initiative would “greatly advance our common goal of helping to continuously advance societal resilience globally”.

The utilisation of an industry-wide standard for property risk reinsurance models aims to assist with solving the existing data and model interoperability challenges in the re/insurance market.

Martin Bertogg, head of Cat Perils, Cyber and Geo at Swiss Re, said: “Globally shared data formats are an important step to overcome barriers for consistency, processing efficiency and a transparent cat risk dialogue.

“Our industry has an urgent need to take out non-value adding friction from its production chain. By supporting OED, we take an important step to facilitate more insurance risk transfer.”

Jörg Steffensen, general manager, Group Risk Management at Hannover Re, added: “The new OED Standard enables not only a close interoperability between different risk stakeholders but also supports a wide field of open source projects in academia.

”The new standard is a major step forward in creating more resilience to natural catastrophes around the world and closing the protection gap.”

The OED Standard for property and extension to cyber and casualty risks, is helping to drive further innovation in the risk modelling space. Its benefits include:

  • One consistent, community-owned market standard for catastrophe risk data.
  • A significant reduction of resource strain in data processing and formatting.
  • An improvement in high-quality data transfer between users of multiple models and systems.
  • Better access to credible risk management data for underserved and disadvantaged communities.
  • An overall enhancement in the digitalisation of the insurance industry.
  • Improved risk perspective through less reliance on any particular model developer.
